A concealed hook structure for a four-wheeled vehicle

Abstract

This utility model discloses a hidden hook structure for a four-wheeled vehicle, including a frame and fixing components. Two fixing components are provided, spaced apart horizontally. A hook base is located at either the front or rear end of the fixing components, and the hook base has a hook portion extending in a front-rear direction, positioned below the fixing components. Compared to existing technologies, this utility model hides the hook below the fixing components, achieving a concealed function. This not only improves the overall aesthetics but also prevents the hook from bumping into people or objects, ensuring user safety and extending the hook's lifespan.

Description

Technical Field

[0001] This utility model relates to the field of four-wheeled vehicle technology, and in particular to a hidden hook structure for a four-wheeled vehicle. Background Technology

[0002] Four-wheeled vehicles, as an assistive rehabilitation device, are widely used in the field of physical rehabilitation to help users (such as the elderly, postoperative patients, or those with limited mobility) with walking training and daily activities. During the rehabilitation process, users usually need to carry some assistive items, such as medicine kits, water bottles, and rehabilitation equipment. Therefore, the hook structure has become an indispensable functional component in the design of four-wheeled vehicles.

[0003] Based on the above, in existing technology, the hook is fixed to the frame. While this hook design serves to secure items, it is aesthetically unappealing, and the protruding hook is susceptible to bumping into the user or other objects. Bumping into the user could cause injury, while bumping into other objects could damage the hook. Further improvements are needed. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a hidden hook structure for a four-wheeled vehicle.

[0005] A concealed hook structure for a four-wheeled vehicle designed for this purpose includes a frame.

[0006] Two fasteners are provided, spaced apart on the left and right sides;

[0007] A hook base is provided at either the front or rear end of the fixing member, and the hook base is provided with a hook portion extending in the front-rear direction, the hook portion being located below the fixing member.

[0008] Preferably, the hook base is provided with a connecting base, which is detachably connected to the fixing member.

[0009] Preferably, the fastener is a pipe, and the fastener has an opening at at least one end to form an installation port;

[0010] The connecting base is movably inserted into the mounting port;

[0011] The front-to-back projected area of ​​the hook base is larger than the area of ​​the mounting opening, so as to cover the mounting opening.

[0038] See Figures 1-7 A concealed hook structure for a four-wheeled vehicle includes a frame 10 and two fixing members 20 spaced apart. A hook base 30 is located at either the front or rear end of the fixing members 20, and each hook base 30 has a hook portion 310 extending in the front-rear direction, positioned below the fixing members 20. This invention conceals the hook beneath the fixing members, enhancing its aesthetics. Furthermore, this design prevents the hook from bumping into people or objects, ensuring user safety and extending the hook's lifespan.

[0039] See Figure 3 The hook base 30 is provided with a connecting base 320, which is detachably connected to the fixing member 20.

[0040] See Figure 3The fixing member 20 is a pipe, and at least one end of the fixing member 20 is open to form an installation port 210. The connecting base 320 is movably inserted into the installation port 210. The front-to-back projected area of ​​the hook base 30 is larger than the area of ​​the installation port 210, so as to cover the installation port 210. In this embodiment, since the pipe is open, the purpose of the front-to-back projected area of ​​the hook base 30 being larger than the area of ​​the installation port 210 is that after the connecting base 320 is connected, the hook base 30 can cover the installation port 210 to avoid the installation port 210 being exposed and affecting the aesthetics, thereby improving the overall aesthetics. The hook base 30 serves as a decorative cover.

[0041] See Figure 5 The connecting base 320 is provided with a first connecting hole 330, and the fixing member 20 is provided with a second connecting hole 200 communicating with the first connecting hole 330. A locking bolt 60 passes through the second connecting hole 200 and is threadedly connected to the first connecting hole 330. In this installation embodiment, during assembly, the connecting base 320 is inserted into the mounting opening 210 and inserted into the constrained position, and then the locking bolt 60 is threaded through the second connecting hole 200 and threadedly connected to the first connecting hole 330 to achieve a fixed connection.

[0042] Furthermore, the connecting base 320 and the mounting port 210 are either interference-fitted or snap-fitted. An interference fit means the connecting base 320 is inserted into the mounting port 210. A snap-fit ​​means the connecting base 320 is snapped into the mounting port 210.

[0043] See Figure 5 The hook portion 310 is provided with a downwardly recessed limiting groove 311. The function of the limiting groove 311 is to constrain the hung item. For example... Figure 3 When the hanging strap 510 of the object 50 is attached to the hook part 310, the hanging strap 510 can fall into the limiting groove 311, which plays a certain role in preventing it from falling off.

[0044] See Figure 1 A seat cushion element 70 is connected to the two fixing members 20 on the left and right sides. The seat cushion element 70 is part of the four-wheeled vehicle and its function is to raise the seat for the user. When the user pushes the four-wheeled vehicle for rehabilitation exercises, he / she can sit on the seat cushion element 70 to rest.

[0045] Furthermore, the seat cushion element 70 is a piece of fabric.

[0046] See Figure 6 and Figure 7The frame 10 includes a first side frame 101 and a second side frame 102. Connecting rods 120 are rotatably connected to the first side frame 101 and the second side frame 102, respectively. A pivot 170 is provided at the middle of the two connecting rods 120, connecting them to each other. The connecting rods 120 are rotatably arranged relative to the pivot 170. The connecting rods 120 are connected to the fixing member 20. A connecting member 130 is rotatably connected to the connecting rod 120 connected to the first side frame 101, and the connecting member 130 is rotatably connected to the second side frame 102. An abutment member 110 is provided on the first side frame 101, abutting against the fixing member 20. A locking hook 140 is rotatably connected to the connecting rod 120 connected to the first side frame 101, and a locking pin 160 is provided on the connecting member 130. The locking hook 140 can engage and lock with the locking pin 160. In this embodiment, the left and right first side frames 101 and second side frames 102 can be folded for storage. In the unfolded state, the locking hook 140 engages with the locking pin 160 to lock and restrain the rotation of the two connecting rods 120, thereby keeping the frame 10 in the unfolded state.

[0047] Figure 6 and Figure 7 This is the unfolded usage state of the four-wheeled vehicle. In this state, the two connecting rods 120 are unfolded and the locking hook 140 is engaged and locked with the locking pin 160. When folding, the locking hook 140 and locking pin 160 are released, and the first side frame 101 and the second side frame 102 are driven to close and fold together.

[0048] Furthermore, an elastic element is connected to the connecting rod 120 on which the locking hook 140 is provided. The elastic element applies a force to the locking hook 140, so that the locking hook 140 is kept in a locked state with the locking pin 160.

[0049] Furthermore, the elastic element can be a tension spring or a torsion spring.

[0050] See Figure 6 and Figure 7 The function of the abutment 110 is to constrain the downward movement of the fixing member 20. When the frame 10 is fully extended, the fixing member 20 is located above the abutment 110 and the two abut against each other, thus constraining the rotation angle of the connecting rod 120 to ensure the extended state of the frame. When switching from the extended state to the folded state, the rotation of the connecting rod 120 causes the fixing member 20 to move upward away from the abutment 110.
